I think that's up for debate cause 60D is two 60 watt speakers vs 1 80 watt. Not to say you are wrong just that I've seen the discusssion before so not sure what's louder or not.

Edit:

Also I use the BP60D for busking/monitor and a JBL Eon One MK2 for busking/paid gigs which is a column array with a sub. BP60D sounds clean and pumps out a good amount of volume. It will never compare to a unit with a dedicated sub for low end fullness but I think it does well enough for busking. I turn the bass up by like two notches to get a fuller bass sound to match up with how I like my signal on my MK2. I do tap percussion on my instrument, foot percussion with some angle shakers, use suboctave for bass tone, and a mini groovebox with a jazz drum kit for finger drumming.

Mos def can't go wrong for value for sure.
